RIVERSIDE – The final defendant in the case of an international online child pornography bulletin board was convicted today in federal court in Riverside.

Billy Wade Carroll, 51, of Dayton, Ohio, faces a mandatory minimum sentence of 35 years and could receive a life sentence for his conviction of one count of conspiracy to advertise, solicit, transport, distribute, receive and possess child pornography and a second count of committing a child pornography offense while being required to register as a sex offender in Ohio.

Sentencing is scheduled for Jan. 9.

Carroll is the last of 16 members of the Lost Boy bulletin board in the United States who were initially charged in the case, said Thom Mrozek of the U.S. Attorney’s Office. Fourteen have been convicted and another died while in custody.

The case began when the Los Angeles-based Sexual Assault Felony Enforcement Team arrested a North Hollywood man, Mrozek said.

Carroll was tried by U.S. District Judge Virginia A. Phillips who is based in Riverside.

The case involved the FBI and international law enforcement agencies from Western and Eastern Europe, Latin America and New Zealand. Of the 35 members, 16 were American.

The board was closed down more than two years ago.

Carroll was an active member who made more than 100 posts between September 2007 and January 2009. He supplied images of child pornography for other members to download and requested other members provide him with particular images he wanted for his child pornography collection.

According to court documents and proceedings, the Lost Boy bulletin board was dedicated to men who had a sexual interest in young boys and was established so its members could trade child pornography.

Lost Boy members also advised each other on techniques to evade detection by law enforcement, including using screen names to mask identities and ways of encrypting computer data.
